Vigil Held After Twin Attacks By Lone Extremist

OSLO, NORWAY - JULY 25: A Norwegian flag is held up amidst flowers as an estimated 100,000 people gather in Oslo town centre for a vigil following Friday's twin extremist attacks on July 25, 2011 in Oslo, Norway. Anders Behring Breivik, 32, claimed that he has "two more cells" working with him as he appeared in court today following a bomb blast at a government building in Oslo and a shooting massacre on nearby Utoya Island that killed at least 76 people in all. The death toll was originally reported as 93. Breivik has been detained for eight weeks, four of which in full isolation. (Photo by Jeff J Mitchell/Getty Images)
